[0002] In recent years, steel companies have responded to national environmental protection policies and actively carried out ultra-low emission transformation. The machine head dust ash produced in the sintering process is the most troublesome problem for enterprises, because this machine head dust ash has the characteristics of light specific gravity, fine particles, and poor water solubility. Some steel companies treat this type of machine head dust ash and steel slag together, but the mixing process is a huge environmental problem. The existing technology is to use a bucket car, which first takes over the machine head dust ash discharged from the ash hopper of the sintering machine, covers the machine head dust ash for transportation, and then dumps the machine head dust ash into the simmering pit. However, the vehicle is bumpy during transportation, which will cause dust and pollute the road and air. In addition, when the bucket car dumps the machine head dust ash, due to the light specific gravity, fine particles, inertia, etc. of the machine head dust ash, a large amount of dust will be generated, and the visibility in the workshop is extremely low, which not only affects the working environment, but also causes great safety hazards in equipment operation.
